In August, the National Oceanic and Atmospheric Administration (NOAA) issued its updated forecast for the 2024 hurricane season. Significantly warmer than usual surface temperatures in the Atlantic Ocean, which come largely as a result of human-caused climate change. Why are the oceans so warm and fueling this rapid intensification?
Guest commentary by Robert Hart, Kerry Emanuel , & Lance Bosart The National Weather Service (NWS) and its parent agency, the National Oceanic and Atmospheric Administration (NOAA), delivers remarkable value to the taxpayers. Findings on changes in the private weather industry, 2017.
Here we start by taking the Greenland mass loss rate into the ocean, times the temperature difference between the meltwater and the water it replaces. For the part entering the ocean as ice, we must also consider that to melt ice requires energy. Greenland ice melt. or other estimates). References. Trenberth, K. & Fasullo, J.
Manabe’s subsequent work led to the development of the GFDL GCM, initially just including the atmosphere, but eventually with an ocean, and then the transient results shown in Manabe and Stouffer (1993). The basic issue stems from the different timescales of the ocean and atmosphere. 1975) , and Bryan et al.
It’s an arresting graphic, and follows in from the record high ocean surface temperatures that were being reported a month ago. Since the seasonal cycle over land is much larger than over the ocean (smaller heat capacity, and less evaporation), that means that the seasonal variations in the north outweigh the variations in the south.
However, on the level of basic physical reasoning, it is of course a no-brainer that warming will cause land-ice to melt (and melt faster as it gets hotter) and ocean waters to expand, so sea-level rise is the inevitable result. meters of rise by 2100. The Long Term Future.
The ocean is a vast and beautiful home to so many incredible animals. However, a growing number of creatures are finding their ocean homes polluted by trash. Every year, 11 million metric tons of plastics enter our ocean. Together, we can keep plastics out of our ocean and away from ocean wildlife. Hermit Crabs.
2021) show that the trends in the EEI derived from CERES match what you get from the changes in ocean heat content. Satellite-derived trends in EEI compared to estimates from changes in ocean heat (Loeb et al., Koonin, "Earth's Albedo 1998–2017 as Measured From Earthshine", Geophysical Research Letters , vol. Shoumko, S.
Ocean Toxin a Heartbreaking Threat for Sea Otters. Domoic Acid Raises Risk of Fatal Heart Disease for Otters in a Warming Ocean. The world’s ocean temperatures in 2020 were the third highest on record, and all five of the oceans’ hottest years on record occurred in the past five years. . Over-exposed otters.
LISA LINOWES and ERIC TURNER on behalf of the SAVE RIGHT WHALES COALITION Since 2016, the National Oceanic and Atmospheric Administration (NOAA) has declared three Unusual Mortality Events (UME) involving large whale species in the Atlantic Ocean. The UMEs for the humpback and minke whales include deaths in 2016 and 2017, respectively.
They are also marine outfalls, which means the only treatment the sewage receives before being pumped into the ocean is maceration through a three millimeter sieve to remove solids and grit. Further studies found some of these chemical compounds accumulating in fish in False Bay, on the Indian Ocean side of the city.
By Emma Foehringer Merchant When wildfires spread through parts of Northern California wine country in 2017, they melted electronics, combusted cars and exploded propane tanks. The fires sent acrid smoke billowing into the sky, its footprint wafting over the state and extending for 500 miles into the Pacific Ocean.
degrees Fahrenheit between 1951 and 2017.” Now, though, climate is changing rivers, lakes and oceans, forcing a renegotiation of our relationships to those bodies of water. ” Moreover, “average temperatures in the Great Lakes region rose 2.3 ” Climate change is hitting home right in the middle of the country.
He makes his living on the Turnbridge Plantation in his hometown of Hardeeville, South Carolina, 30 minutes from the Atlantic Ocean. Atlantic sea levels are rising three to four times faster than the global ocean average. Today, Carolina Gold is cultivated by only a handful of small-scale farmers. .
The physics-based models describe how energy flows through the atmosphere and ocean, as well as how the forces from different air masses push against each other. Furthermore, the volume of the oceans increases from the melting of land ice. The global sea level acts like the mercury in a thermometer because warmer water expands.
2020), and can cause an increase in vertical wind shear over the Atlantic ( Kossin 2017 ; Ting et al. 390-393, 2017. Bennartz, "The Role of Aerosols in the Evolution of Tropical North Atlantic Ocean Temperature Anomalies", Science , vol. All three of these factors have a powerful quelling effect on tropical storm formation.
For 2022, the National Oceanic and Atmospheric Administration (NOAA) predicted a season with above normal activity on its August 4 updated forecast , calling for 14-20 named storms. .” After all, we hardly had storms or hurricanes in the news for the past 3 months.
Ocean Conservancy has compiled the data collected during this global volunteer effort on behalf of ocean health since the ICC’s start in 1986. Now, a new collaboration between Ocean Conservancy, PADI AWARE Foundation and scientists at CSIRO has resulted in the first global map of plastic hotspots. Never miss an update.

By Deborah Pirchner, Frontiers science writer Image: Rob Lachlan As ocean temperatures rise, corals can lose their color due to heat stress. One of the worst mass bleaching events occurred in 2016 and 2017 on the Great Barrier Reef, causing bleaching on 91% of the system’s reefs.
The idea is to boost the natural process by which carbon dioxide in precipitation reacts with soils and rocks to form bicarbonate ions, which eventually find their way into oceans via rivers.
Based on the most comprehensive winter study to date, conducted in the Southern Ocean during July and August 2017, scientists were able to show that phytoplankton were indeed active during the icy cold and dark winter months. Read the full story from Stellenbosch University.
Six environmental groups launched the proceeding challenging the stay after EPA published notice of the stay in the June 5, 2017 issue of the Federal Register. filed June 5, 2017; emergency motion for stay granted July 3, 2017). June 29, 2017). June 28, 2017). June 28, 2017). filed June 9, 2017).

Meanwhile, less than 100 miles away from the governor’s office as the gull flies, a strong wind was blowing over the ocean south of Martha’s Vineyard. 1 megawatt-hour is 1,000 kilowatt-hours.)
In the summer of 2017/18, 50 children died compared to this season’s 20. Later, as the heavier winter rains set in, the pollution is flushed from the streets and fields into the rivers and ocean, coinciding with a drop in reported diarrhea cases. Compared to the last pre-covid month, February 2020, the increase is 80%.

About 90% of its farms are considered “family owned,” according to the 2017 US Department of Agriculture farm census. From 2002 to 2017, the most recent USDA farm census, the number of farms in Kings County declined 16.6%. Like its neighbors, Kings is intensively farmed. The data show that’s already happening.
They start their lives in freshwater, migrate to the ocean for most of their lives, and then return to freshwater rivers and streams to spawn and die. Before salmon enter the ocean, they must find clean and cold waters to forage and grow.
A high proportion of plastic waste ends up in seas and oceans – estimates suggest that more than 250,000 tons of plastic debris are currently floating around in oceans all over the world. . Plastics are taking over the oceans.
Abandoned, lost or discarded fishing gear—also known as ghost gear—is one of the most visually arresting forms of ocean plastic pollution. That’s why the Global Ghost Gear Initiative (GGGI) first released the Best Practice Framework for the Management of Fishing Gear (BPF) for Capture Fisheries, or C-BPF, in 2017. Never miss an update.
In addition, it stores vast quantities of freshwater that if released to the ocean would rise sea level by tens of meters and interfere with saline-driven ocean currents that transfer heat around the planet. In the ocean, 19 marine heatwaves have been recorded between 2002 and 2018. Prof Martin Siegert in Antarctica.
Like many other women-led and community-based organizations in Puerto Rico, Taller Salud has taken up the recovery and resilience development in their communities to face the acute climatic, economic, and social crisis that Puerto Rico is facing after the devastation caused by Hurricane María in 2017.

The global scale of plastic production means that these tiny fragments of plastic are now ubiquitous, and scientists fear that ocean currents will cause plastic to accumulate in the Arctic, damaging ecosystems. It is even found in the polar oceans and the deepest ocean trenches.” and 10cm in size) for a different study.
In the past few years, physicists have begun to realize that it could have a major role in fluid dynamics – the Earth’s oceans, for example, or plasmas, or the biological cells in fluid-like “active” matter. First of all, the slim layers of the Earth’s atmosphere and oceans can be approximated as 2D. But how many waves?
Over a decade, from 2007-2017 , the direct costs of extreme weather events to the federal government was $350 billion. However, during half that time, from 2015-2021, the direct costs to federal government for disasters was $315 billion.
By Delaney Dryfoos In San Felipe, a fishing town on the northeast edge of Baja California, the use and transportation of gillnets have been banned by the Mexican government since 2017 as a measure to protect the rare vaquita porpoise.
